I wanted to set up a SPI communication with a panel. Unfortunately I didn't succeed because the program comes to an end when the SPI interface is initialized.

- I use an Arduino Uno Board.- Every 500ms the Arduino LED (Digital 13) is controlled.- Before the endless loop the SPI interface is initialized.- No further SPI activities to follow

If the SPI interface is deactivated - SPI is not initialized -, the program runs without objection. the LED flashes in the preset frequency. If I activate the SPI interface, the program gets stuck with this expression.

" Are you 100% sure the SPI bus is working and you are addressing right device? "-> I am sure that the SPI interface doesn't work under flowcode 8, because it works under Arduino-IDE with the same display.

" On FC7 i remeber the ENC ethenet module had habit to stuck the program when trying to initialize the module, when it was not present... Could this be same thing? "-> If this is the problem, the display should also not work under Arduino IDE.

" Have you tested that the display works? "-> I am sure that the display will work, because with the Arduino IDE the display will work (the structure has not been changed).
